APPARATUS FOR USE IN LEARNING READING AND ARITHMETIC Filed Nov. 5,.1 944 3 Sheets-Sheet 2 Patented Feb. 4, 1947 PATENT OFFICE APPARATUS FOR USE IN LEARNING READING AND ARITHMETIC Lawrence Frederick Donner, London, England Application November 3, 1944, Serial No. 561,726 In Great Britain October 21, 1943 24} Claims.

This invention relates to educational appara-' tus, and apparatus for playing a game, of the kind comprising bricks, blocks or like pieces, each bearing a numeral, letter of the alphabet or other character, particularly for use by young people and others to facilitate the learning of numbers, letters of the alphabet and other purposes, such as a game of word-making. These bricks, blocks or like pieces, each bearing character, will hereinafter be referred to generally as bricks. The invention is concerned with educational, games and like apparatus of the type (hereinafter referred to as the type described) comprising a plurality of bricks each of four-cornered shape, each havin on one face a numeral, letter of the a1- phabet or other character, and each formed or provided with one or more projections or with one or more recesses for use in assembling the bricks in one or more rows to form numbers, when the bricks carry numerals, or to form words, when the bricks carry letters of the alphabet.

It has heretofore been proposed to provide apparatus of the type'described, in which each brick had a plurality of lateral dovetailed projections and corresponding grooves for interlinking the bricks side by side to provide a word or words; in this earlier construction each brick was similar to every other brick, except for its marking, so that they could also readily be assembled side by side in a row in such a manner that the letters on them did not form words, but were jumbled. The present invention has for its main object to provide an improved construction of apparatus of the type described, to assist children in learning to count, as from one to ten or any other consecutive series of numbers, and in learning the letters of the alphabet in the correct order, and in learning to read Words, and arranging letters in the correct order to form words.

According to the invention there is provided educational and other apparatus of the type de-,

scribed comprising a plurality of members that lie or are arranged to lie one against another, some or all of which members constitute bricks having characters on their upper faces, two faces 4 of which members that are adjacent or are to be adjacent one to another are formed respectively with one or more projections in the form of ribs,

and with one or more corresponding recesses in the form of grooves, which co-operating projections and recesses of one pair of members diifer in arrangement, shape, or size from those of another pair so that the bricks, when assembled, will lie only in one predetermined order in relation one to another.

A plurality of bricks having characters on their upper faces constituting each a male member may be arranged to co-operate with various parts of a female member common to all the bricks.

. Alternatively, a plurality of bricks having characters on their upper faces constituting each a female member may be arranged to co-operate with various parts of a male member common to all the bricks.

Conveniently, the male or female base member for use with a plurality of bricks having characters on their upper faces has the form of a bar whereof its top face has respectively a plurality of ribs or grooves, and is divided in the direction of its length into a plurality of fields or squares arranged in a row each for receiving a piece having grooves or ribs respectively at its underside, at least one rib or groove in each of which field is blanked oil to make it shorter than one or more other ribs or grooves in the same field, the

blanked ofi' portions of which ribs or grooves difier in position and/or size in the various fields.

In some cases at least one rib or one groove in each field is narrower than one or more ribs or grooves respectively in the same field, and the side by side on a base member common to them all, and each field in a row may differ as to its projections and/or recesses from all the other fields in the same row and one or more other rows.

An end field in a row may have continuous ribs and continuous grooves between the same, which end field may serve for mating with a blank memher.

The invention also provides apparatus as set so forth for use with an alphabet of twenty-six 5 members or partition walls into two or more areas each comprising a plurality of rows of fields arranged in parallel relation.

Several embodiments of the invention are diagrammatically illustrated by way of example in the accompanying drawings, wherein:

Like reference characters designate like parts throughout the several views.

Referring first to Figures 1 and 2, one form of educational apparatus of the type described, designated generally 20, comprises ten square bricks 21 to 35 for use with a base member 32 which constitutes a female member and is a rectangular bar. This bar 32 has in its top face five continuous longitudinal recesses or grooves whereof the two outer ones are rabbets. These grooves form four lbs 34, 35, 35 and 31, two of which 34 and 3? lie near opposite sides of the bar. This grooved face is divided longitudinally into ten square fields, one for each brick, by nine division lines marked on it, or by nine transverse thin strips of metal or other convenient material let into saw cuts in the bar, as described hereinafter with reference to Figures 3 to 7. In each field a part of one rib is removed so as to blank off part of the same, and corresponding parts of the bricks have the grooves blanked by solid material; each field and its allotted brick have cooperating projections and grooves which are arranged differently from the other fields and their allotted bricks, in order that the bricks can be assembled only in one predetermined order in relation one to another.

The bricks to 3d taken together are equal in area at their underside to the total area of the fields, and they are preferably the same thickness as the bar 32. Each brick is a male member and has on its bottom face a plurality of projections in the form of tongues or ribs so arranged that each brick is a counterpart of one of the fields. As shown in Figure 2, the underside of the row of bricks arranged in correct numerical order is formed with live longitudinal projections in the form of ribs or tongues 5!, 42, 43, 4c, 45 corresponding to the five grooves in the bar 32. These ribs, apart from the divisions between the bricks, are all continuous, but the four grooves fill, 48, 49, 5!! between them are discontinuous. In the end brick 21, the groove 49 is blanked off by material at 51 to enter into a gap at 52 in'the rib shown in Figure 3. In the bricks 22 and 23, the groove 5B is blanked ed by material at 53 and 54, respectively, to enter a gap at 58 in the rib 34. In the bricks 24 and 25, the groove 55 is blanked off by material at 57 and 53, respectively, to enter a gap at 5!! in the rib 35. In the bricks 25 and 2?, the groove 48 is blanked off by material at El and 52, respectively, to enter a gap at 64 in the rib 35. In the bricks 28 and 29, the groove 41 is 4 blanked off by material at 65 and 86, respectively, to enter a gap at 63 in the rib 3?. In the end brick 38, the groove 48 is blanked off by material iii to enter a gap at T2 in the rib 3-5. Consequently when all the ten bricks are placed level on the bar 32 with their projections entered into the recesses they must lie in a predetermined order, in which numerals l to 9 and 0 will be in the ,correct order. If letters of the alphabet e. g. A to J, are marked on the bricks instead of numerals they also will be in the correct order. By using the described apparatus in this way a child may be assisted in learning numbers and letters of the alphabet.

The apparatus shown in Figures 3 to 7 is intended particularly for use with bricks having letters of the alphabet marked on their top faces arranged in order on a base member designated generally 74. This base member is a female member which comprises three bars 32, 76 and 58 joined together side by side in any convenient manner, as by two tenon and mortice 89, 82, and it may have at the bottom a layer of fabric 84, such as baize, or the like. The bar 32 and the bricks to be used with it have been described above with reference to Figure 1. The bar 76 is similar to the bar 32, but differs therefrom in that, as is apparent particularly from Figure 4, the width of its rib I36 differs slightly from the width of the corresponding rib 34, while its ribs I35, 136 and 53! substantially correspond in width to the ribs 35, 36 and 37, respectively. The bar 78 is similar to the bar 15, but differs therefrom in that it has only three libs 234, 235 and 236, and has no rib corresponding to the rib I37 of the bar 76. It is apparent in Figure 3 that gaps in the ribs of the two bars H5 and i8 difier in position, and also differ in position from the gaps in the ribs'of the bar 32.

The bricks for use with the bars '16 and 18 are male members and have projections in the form of ribs or tongues for entering into the recesses of those bars, as well as recesses in the form of grooves for receiving parts of the projections of the bars. Two such bricks I28 and 228, corresponding in position to the brick 28, for use with the bars It and i8, respectively, are shown in cross-section in Figure 5. These two bricks I28, 228, and also all the other bricks for use with the bars 16 and 18 have each a groove blanked off with solid material to enter a gap in a rib of the respective field on which the brick is to be placed in its correct position on the base member 14.

The fields are defined by nine thin transverse strips Hi to es of metal or other convenient material let into saw-cuts in the ribs of the base member, which strips prevent bricks on the bars from being slid along a bar from one field to the next in both directions. The ten fields of the bar 28 defined in this manner are designated HM to H0 in Figure 3.

As there are only twenty-six letters of the English alphabet, and the two bars 32 and I6 have each ten fields for twenty lettered bricks, the bar l8 need have only siX fields for six lettered bricks. Consequently, as shown in Figures 3 and '7, the two strips 9i and 99 need not extend across the bar 18, so that this bar has at its ends larger spaces I 52 and lit, in which the grooves and ribs are continuous, for receiving two oblong unlettered members H5 and H3, respectively, each equal in size to two of the lettered bricks. These blank members H6, H8 have at their underside continuous ribs and grooves for co-operating with the grooves and ribs, respectively of the two larger spaces l i2, H 3, t e area of each of which is substantially equal to the area of two of the square fields. Preferably these blank members 1 iii and l is are fixed in position, e. g. detachably, on the base member i i, to ensure that no lettered brick can be improperly placed on either of the spaces H2 and! Hi.

It will be appreciated that as the male and female members each has projections and recesses, the base member it described above as a female member may be regarded as a male member, in

which case the bricks will be regarded as cooperating female members.

It will be observed from Figure 3 that the ribs ids and are shown wider than the other ribs, and thegrooves between some of the ribs are shown wider than those between other ribs. In this way provision is made for a large number of possible combinations of dissimilar projections and recesses of the co-operating male and female members.

Referring now to Figures 8 to 10 showing a word-building apparatus of the-type described, a male base member i2? a short middle upstanding partition wall @522 dividing its top face into two equal areas, each comprising fifteen fields arranged in five rows, with three fields in each row. Two of these fields and part of a third are shown at E and 523 in Figure 9. Projections or ribs l3i and N2 of the fields 5251, IN and respectively, correspond in arrangement to the rigs of the fields till, it}? and tilt shown in Figure 3, but diifer therefrom in that they do not extend to the outside edge of the base member, and are divided in the direction of th length at the margins of the fields not by us, but spaces as'shown at 33. The bricks constituting female members to be used with each area of the base member are lettered to form three-letter words, and each has recesses in its underside to correspond with the projections of the correct field on which it is intended to be placed. The brick Mil shown in Figure 10, for example, corresponds to the brick 22 shown in Figure 1, and has recesses to receive the ribs 135 of the field I25 shown in .l. igure 9. It will be seen that the middle letters of the five rows of bricks at opposite sides of the partition wall 522 are the five vowels arranged. in their correct order. wall i22 may differ from those at the opposite side if desired. Also the bricks may bear numerals instead of letters. Further base members may have only one area divided into fields. or

more than two such areas with partitions or the like between them.

In some cases, some of the grooves may be made narrower than others to provide for a large number of possible combinations of projections and recesses.

In order that the projections on one brick may differ from those on another, one or more of such projections on one side of a brick may diifer in size or or in both size and shape from one or more ot are on the same side of the same brick.

The bricks and also the members may be of'any convenient material. e. a. wood, metal or any convenient moulded substances, such as lastic.

The described constructions of apparatus are also adapted for use in playing a game and for amusement purposes, although they are primarily intended for educational purposes.

Various modifications may be made In the dc- Obviously the words at one side of the he tails of construction described above without departing from the invention. For example, the letters, numerals or other characters on the bricks may be applied to them either directly, as by painting or printing or embossing, or by means of a panel affixed to them. Also each brick may be of a different colour from one or more others, or in one apparatus all the bricks may be of the same colour. Further, when the base member i shown in Figure 3 is moulded the strips of metal may be substituted by moulded portions.
